BBC2 has a new celebrity chef – model Sophie Dahl – who will front a new show from Jamie Oliver's company Fresh One Productions.

Dahl, who will sit alongside Delia Smith and Nigella Lawson on the channel's roster, will cook up "delicious recipes and reminisce on her own personal food memories" on her unnamed six-part series, which will screen next year.

Each episode will focus on a different theme and Dahl will "revisit treasured and nostalgic places giving insight into the resonance and meaning behind each recipe".

As well as modelling, Dahl, who is the granddaughter of children's writer Roald Dahl, is a best selling novelist and has written about food.

"For me, food is more than just fuel; it's a joy and an adventure," she said.

"Cooking often serves as an emotional barometer, and with this show we will run the gamut – from a solo dinner that suits melancholy to a homecoming feast for 20, it's cooking with an anecdotal thread, irreverent, unpredictable and not without flaw."

Janice Hadlow, the BBC2 controller, added: "Not only are her recipes fantastic, she's honest, funny and warm. And she'll be in great company alongside our other homecooking heroines, Delia and Nigella."

The series was commissioned by Jo Ball, the BBC commissioning editor for factual features, with Lisa Edwards and Alison Kirkham executive producing.

Meanwhile, Channel 4 has commissioned a new peaktime comedy quiz show about food hosted by Sue Perkins.

The Big Food Fight will see Perkins joined each week by River Cottage chef Hugh Fearnley-Whittingstall, who will be one of two team captains. His opposing captain will be a different guest each week, with other names joining them.

"The Big Food Fight will be a delicious mix of knowledge and foodie facts, with a generous helping of fun," said Channel 4's commissioning editor for features, Andrew Jackson.

Although best known as Mel Giedroyc's comedy partner, Perkins has previous experience tackling culinary subject material having teamed up with food critic Giles Coren for BBC2's The Supersizers Go ... and The Supersizers Eat ..., which both took an irreverent look at the history of food in Britain throughout the ages.

The first five episodes of The Big Food Fight will be made by independent production company Betty in association with Keo films. The series producer is Nick Martin and the executive producers are Liz Warner and Andrew Conrad.
